WITH spectacular dunks and pressuring defence, the US Olympic team of NBA stars routed Tunisia 110-63 on day four while France edged Argentina in a showdown of NBA teammates Tony Parker and Manu Ginobili.

Carmelo Anthony and Kevin Love each scored 16 points and US college star Anthony Davis, the No.1 pick in June's NBA Draft, added 12 points with some high-leaping dunks to help the Americans roll to victory.

African champions Tunisia, led by Macram Ben Romdhane's game highs of 22 points and 11 rebounds, led 15-12 before the Americans scored the next 14 points to seize the advantage for good.

"We figured it out," Anthony said. "We didn't get worried. We knew we could take them."

Parker, playing against San Antonio Spurs teammate Ginobili for the first time in their careers, scored 17 points to lead France to victory over Argentina, 71-64. Ginobili scored a game-high 26 points in a losing cause.

"After 800 games paying together, playing against each other was something different," Ginobili said. "When the ball is in the air you just try and compete."

Parker was the key to victory for France, scoring six points in a row after Ginobili pulled Argentina within 60-58, two of them on a layup when he sped past his helpless NBA teammate.

"It's a big win," Parker said. "Argentina is a very good team and hopefully we can build on that. It's awesome, I feel very proud. I've been working hard."

It was France's first victory over Argentina in five tries in Olympic and World Championship competition.

Nicolas Batum added 14 points, Mickael Gelabale had 13 and Nando de Colo - who will join the Spurs next season - scored 11 for France, which moved level with Argentina, Nigeria and Lithuania at 1-1 in Group A behind the 2-0 US team.

The Americans next play on day six against Nigeria while France will meet Lithuania and Argentina will face Tunisia in other Group A matches.

In other games, Russia's Andrei Kirilenko scored 16 points and grabbed nine rebounds while Alexey Shved added 14 points and six assists to power Russia over China 73-54.

"We are in pretty good shape," Kirilenko said. "We've got a lot of confidence and momentum but it's not going to be easy."

Up next for the Russians will be Brazil, which missed 18 of its first 20 shots but still rallied to edge Britain 67-62 while Linas Kleiza scored 13 points to lead Lithuania over Nigeria 72-53.
